平煤二矿沿空留巷工业试验

gainst the feature of miscorrelation of driving and mining and wall rock deformation in roadway in No.2 Mining Industry Company in Ping Ding Shan, the author carried out industrial experiment of high moisture quick setting material for roadway backfilling. According to the industrial experiment, this paper mainly introducing the scientific process of fulfilling, and raised the implementation of using reinforcement fabric cover for filling mass, on this basis, make a second bolt and cable anchor for secondary support, which is an effective technical system of controlling the deformation of surrounding rocks. It is proved that using quick setting material for roadway backfilling is beneficial for reducing the tunneling rate, improving coal recovery, serving for the next face, which has significant technical and economic benefits for No.2 Mining Industry Company in Ping Ding Shan.
